DETAILED DESCRIPTION

FIG. 1 is a schematic illustration of a perspective view of anelectrical connection assembly 100 including an electrical box 110 andan electrical connector 120. The electrical box 110 and electricalconnector 120 provide a structure having junction points to mechanicallyand electrically connect one or more devices (not shown) with anelectrical current supplied to or from the electrical box 110 (e.g., viaan electrical wire, not shown). For example, the electrical box 110 andelectrical connector 120 can join electronic devices (e.g., panels withdevices having decision making capability defining a closed loopsystem), electrical devices (e.g., panels without decision makingcapability), and electromechanical devices (e.g., motor load) with anelectrical current supplied to or from the electrical box 110. Theelectrical box 110 and electrical connector 120 can also serve as ajunction box joining one or more electrical wires.

The electrical box 110 and electrical connector 120 can be employed in avariety of locations where electrical distribution is desired includingfactories, commercial buildings, and industrial facilities.Additionally, the electrical box 110 and electrical connector 120 can beemployed indoors or outdoors and can be provided for permanentinstallation (e.g., in a building) or for temporary installation (e.g.,at a construction site). Unless otherwise noted, the electronicconnection assembly 100 of the present disclosure including theelectrical box 110 and the electrical connector 120 can be employed in avariety of applications for electrical distribution and controlincluding residential and commercial applications with a variety ofelectronic devices (e.g., panels with devices having decision makingcapability defining a closed loop system), electrical devices (e.g.,panels without decision making capability), and electromechanicaldevices (e.g., motor load).

Throughout the disclosure, the electrical box 110 and electricalconnector 120 are schematically illustrated with the understanding thata variety of electrical components (e.g., wires, capacitors, inductors,transformers, reducers, amplifiers, fuses, switches, connectors,detectors, sensors, transducers, resonators, semiconductors, cables,timers, tubes, suppressors, terminals, etc.) oriented to provide one ormore operations or functions with respect to distribution and control ofelectric power to an/or from the electrical box 110 and the electricalconnector 120, for example, between one or more active devices and oneor more passive devices, can be provided in further embodiments withoutdeparting from the scope of the disclosure.

The electrical box 110 includes a housing 111 having an outer surface112 and an inner surface 113. The inner surface defines an internalvolume 114 of the housing 111. In some embodiments, a cover (not shown)can be provided to isolate the internal volume 114 from an externalenvironment in which the electrical box 110 may be employed. Forexample, in some embodiments, the housing 110 can define an enclosureincluding the internal volume 114 in which one or more electricalcomponents (switches, dimmers, controllers, electrical junctions, notshown) can be contained. The housing 111 can be manufactured from ametallic, plastic, polymeric or other suitable material oriented toprotect the electrical components from a variety of external forces,elements, and contact. Moreover, the electrical box 110 can be providedin a variety of shapes (e.g., rectangular, cuboidal, polyhedron, etc.)and sizes (e.g., small, medium, large) without departing from the scopeof the disclosure.

The electrical box 110 can include one or more apertures 116 oriented toprovide access into the internal volume 114 of the housing 114. Whilethree apertures 116 per side of the housing 111 are shown in theillustrated embodiment of FIG. 1, in further embodiments, one apertureor a plurality of apertures can be provided. A disc 115 (e.g.,knock-out) can be positioned to obstruct the aperture 116, therebyrestricting or preventing access into the internal volume 114 of thehousing 111. The disc 115 can be attached to the housing 111 with afastened connection, a threaded connection, or other temporary orremovable link that can maintain the disc 115 in position relative tothe housing 111 obstructing the aperture 116 until the link is broken,and access through the aperture 116 is enabled. Typically, a technician(e.g., electrician, maintenance worker, engineer) can remove (e.g., hit,pry, bend, tap, contact) the disc 115 with a tool (e.g., screwdriver,mechanical tool, hand, finger) to provide access into the interiorvolume 114 of the housing 111 through the aperture 116. After removingthe disc 115, the technician may dispose of the disc 115 as it may nolonger provide utility with respect to the electrical box 110.

Further, after removing the disc 115, the technician can then connect aconnector (not shown) to the housing 111 to facilitate placement of oneor more electrical wires or cables (not shown) into the aperture 116.The connector (not shown) can support the electrical wire and retain theelectrical wire within and connected to the electrical box 110 whileelectrical current is provided to the one or more electrical componentshoused in the electrical box 110. The process of removing the disc 115,attaching a connector (not shown) to the electrical box 110, and thenplacing the electrical wire, can be time consuming and cumbersome whenperformed in a variety of environments and when repeated multiple times.Moreover, certain electrical codes may dictate that any apertures 116from which the disc 115 has been removed and through which a wire wasnot subsequently placed, are to be blocked or plugged, thus adding yetanother step and additional inconvenience to the technician.

Optionally, the disc 115 can be removed from the aperture 116 and aconnector (not shown) can be secured to the aperture 116 (e.g., threadedengagement, snap-fit) upon manufacture of the electrical box 110. Forexample, known connectors (not shown) connected to the electrical box byway of removal of the disc 115 and mechanical connection to the aperture116. In other words, to connect known connectors to the electrical box,the disc 115 must be removed to expose the aperture 116. The electricalbox 110 and attached connector can then be supplied to the technician asan assembled unit. While such an approach reduces the number of initialsteps a technician may take to place a wire, as noted, certainelectrical codes may dictate that any apertures 116 from which the disc115 has been removed and through which a wire was not subsequentlyplaced, are to be blocked or plugged. Thus, to the extent one or morediscs 115 are removed such that known connectors (not shown) can beattached to the electrical box 110, unless a wire is place through theexposed aperture 116, the technician would still be required to block orplug the unused aperture 116, again, adding yet another step andadditional inconvenience to the technician.

In addition or alternatively, one or more connectors (not shown) may beprovided inside the housing 111 to retain a cable or wire placed throughthe aperture 116. While such connectors may adequately retain a wire,such connectors occupy at least a portion of the internal volume 114 ofthe housing 111 and, therefore, impede placement of electronic deviceswithin the housing 111 and, likewise, reduce the available space withinthe housing for placement of multiple electronic devices or relativelylarger electronic devices.

Accordingly, it can be appreciated that, for safe and effectivedistribution and control of electric power, connectors for electricalboxes and electrical boxes with connectors are needed to provide one ormore advantages with respect to at least the above-noted deficiencies ofknown boxes and connectors. The present disclosure provides an assembly100 for electrical distribution including an electrical box 110 and anelectrical connector 120 having features that can be provided eitheralone or in combination to facilitate safe and effective electricalconnection and electrical distribution while achieving advantages thatcannot be obtained by known electrical boxes or known electricalconnectors.

FIG. 2 is a plan view of the electrical box 110 and the electricalconnector 120 of the electrical connection assembly 100 of FIG. 1showing the electrical connector 120 attached to the electrical box 110with a fastener 125 (e.g., screw, bolt, rivet, peg, pin, adhesive,material bonding technique, weld). The electrical connector 120 includesa frame 121 that includes a flange 126, and the housing 111 includes arecess 123 (e.g., aperture, notch). The fastener 125 mechanicallycouples the flange 126 of the frame 121 of the electrical connector 120to the recess 123 of the housing 111 of the electrical box 110.

As shown, the electrical connector 120 is fixed to the outside of thehousing 111 without displacing the disc 115 secured in the aperture 116.That is, the electrical connector 120 is mechanically attached to theelectrical box 110 relative to an aperture 116 with the disc 115obstructing the aperture 116 remaining in-tact and unaffected by theattachment of the electrical connector 120. Thus, per some electricalcodes, because the electrical connector 120 is connected withoutdisplacing the disc 115 of the aperture 116, the technician has theoption of (a) removing the disc 115 and placing a wire through theaperture 116; or, (b) leaving the disc 115 in place to obstruct theaperture 116. Either option (a) or (b) can be performed while theconnector 120 is and remains connected to the electrical box 110.

The electrical connector 120 and electrical box 110 of the electricalconnection assembly 100, therefore, eliminate the initial step ofremoving the disc 115 from the aperture 116 and connecting a knownconnector (not shown) to the aperture 116 (e.g., by threaded engagementor snap-fit engagement). Moreover, the electrical connector 120 andelectrical box 110 of the electrical connection assembly 100 alsoeliminate the additional step of plugging or blocking an aperture 116 towhich a known connector has been attached (requiring removal of the disc115) but through which a wire was not subsequently placed.

Further, by fastening the electrical connector 120 to the outside (e.g.,outer surface 112 of the housing 111, the internal volume 114 of thehousing 111 is not occupied by the electrical connector 120 and,therefore, the internal volume 114 provides maximum space for placementof a variety of electrical components and wiring. Thus, the electricalconnector 120 fixed, with fastener 125, to the outside of the electricalbox 110 provides an efficient and versatile electrical connectionassembly 100. Moreover, the electrical connection assembly 100 enablestechnicians to have added flexibility and reliability with respect tothe type of electrical components housed within the internal volume 114of the housing 111 as well as the type and arrangement of wiringconfigurations employed with respect to the electrical connector 120,thereby achieving desired power distribution and control for a varietyof diverse applications.

In the illustrated embodiment, the electrical connector 120 includes oneor more protruding tabs 122 a, 122 b extending from the frame 121 of theconnector 120 and configured to mate with corresponding notches providedon a wall of the housing 111 relative to the aperture 116. Theprotruding tabs 122 a, 122 b function as additional fasteners or hooksthat, along with fastener 125, further secure the electrical connector120 to the electrical box 100. For example, in some embodiments, theprotruding tabs 122, 122 b can be provided as an “L” shape or a “T”shape.

To facilitate fastening of an electrical wire with the electricalconnector 120, the electrical connector 120 can include a retainer 140.As shown in FIG. 3, which illustrates a cross-sectional view of theelectrical box 110 and the electrical connector 120 taken along line 3-3of FIG. 2, the retainer 140 can be fitted, inserted, or formed withinthe frame 121. The retainer 140 can define an insertion path 165extending from a front opening of the frame 121 to a rear opening of theframe 121 adjacent to the housing 111. The insertion path 165 can definea linear or non-linear path and corresponding opening along which one ormore wires can be passed. For example, electrical wires and cables aswell as tools can be inserted into the frame 121 and passed through theretainer 140 along the insertion path 165 into the internal volume 114of the housing 111. The retainer 140 can include one or more teeth 145extending radially inward from the frame 121 to clamp and grip the wire(e.g., an electrically insulated coating or protective sheath of a wire)inserted into the electrical connector 120. Although three teeth 145 areshown radially spaced around the internal boundary of the retainer 140,a single tooth or more than three teeth can be provide in furtherembodiments.

Additionally, the teeth 145 can be angled, and can include a variety ofshapes and structures oriented to clamp and grip a wire includingmechanically flexible or depressible teeth 145 that, when depressed(e.g., by a wire), exert an opposing, spring-back force on the wire toretain the wire within retainer 140 and the frame 121 of the electricalconnector 120. A plurality of retainers 140 can be coupled with acorresponding plurality of frames 121 to provide a single, duplex,triple, quadruple, or other multiple-type electrical connector 120without departing from the scope of the disclosure. The retainer 140 canbe positioned to align with the aperture 116 to define the insertionpath 165 as extending through the connector 120 and into the electricalbox 110. For example, one retainer 140 can be employed for a singleconnector associated with a single aperture 116, two retainers 140 canbe employed for a duplex connector 120 associated with two apertures116, and so forth.

FIG. 4 is a perspective view of a duplex-type electrical connector 120with the electrical box 110 removed for clarity. As shown, the frame 121includes two retainers 140 each of which has corresponding teeth 145.The fastener 125 and the flange 126 along with protruding tab 122 a arealso shown. Similarly, FIG. 5 is an alternate perspective view of theduplex-type electrical connector 120 of FIG. 4 showing the protrudingtab 122 b.

FIG. 6 is a perspective view of the electrical connection assembly 100of FIG. 1 showing the discs 115 (e.g., knock-outs) removed and notobstructing the apertures 116. Unless otherwise noted, it is to beunderstood that such discs 115 could be provided to obstruct theapertures 116 (as shown in FIG. 1) without departing from the scope ofthe disclosure. The electrical connection assembly 100 includes theelectrical box 110 and two duplex-type electrical connectors 120 of FIG.4 and FIG. 5 fastened to the outside of the housing 111 of theelectrical box 110 with fastener 125.

Further, FIG. 7 is a perspective view of an electrical connectionassembly 100 including the electrical box 110 and one duplex-typeelectrical connector 120 of FIG. 4 and FIG. 5 fastened to the outside ofthe housing 111 of the electrical box with fastener 125. FIG. 8 is analternate perspective view of the electrical connection assembly 100 ofFIG. 7 including the electrical box 110 and the electrical connector120.

FIG. 9 is a rear partial perspective view of the electrical connectionassembly 100 including the electrical box 110 and the electricalconnector 120 of FIG. 6 with a portion of the electrical box 110 removedfor clarity. The protruding tabs 122 a, 122 b are inserted through thecorresponding notches 124 a, 124 b without disturbing the disc 115 andfurther secure the electrical connector 120 to the electrical box 100.In some embodiments, the protruding tabs 122 a, 122 b and the fastener125 can securely fasten the electrical connector 120 to the exterior ofthe electrical box 110 such that wires placed through the aperture 116(e.g., after removal of the disc 115) will not pull-out or disconnectfrom the electrical connector 120 or the electrical box 110.

The notches 124 a, 124 b can be provided as a slot or opening in thehousing 111 adjacent to the aperture 116 or integrally formed as part ofthe perimeter (e.g., boundary) of the aperture 116. For example, theaperture 116 may define a keyed or notched perimeter, and the disc 115may define a circular perimeter that, when positioned to within theaperture 116, substantially obstructs the aperture 116 (e.g., incompliance with certain electrical codes) while providing the keyed ornotched opening as notches 124 a, 124 b. Although two protruding tabs122 a, 122 b and two corresponding notches 124 a, 124 b are shown, infurther embodiments one protruding tab and one notch or more than twoprotruding tabs with more than two corresponding notches can be providedwithout departing from the scope of the disclosure.

As shown, the discs 115 are attached to the housing 111 and obstruct theaperture 116 while the electrical connector 120 is also attached to thehousing 110. Additionally, the protruding tabs 122 a, 122 b extendingthrough corresponding notches 124 a, 124 b abut the internal surface 113of the housing 111 to secure the frame 121 to the outside of the housing111 along with fastener 125. The electrical connector 120 and electricalbox 110 are supplied to a technician as a completed assembly 100 withthe electrical connector 120 fixed to the electrical box 110 and withthe discs 115 in place obstructing the aperture 116, as per certainelectrical codes. Upon a decision to insert a wire through a particularaperture 116, the disc 115 can be removed (e.g., at least partiallydisconnected from) the housing 111 to provide the insertion path 165 forinsertion of the wiring through the connector 120, where the wire is beretained by the retainer 140.

FIG. 10 is an exploded perspective view of an embodiment of theelectrical connector 120 showing the retainer 140 separated from theframe 121 for visual purposes. In some embodiments, the retainer 140 caninclude an electrical insulating bushing 150 circumscribing theinsertion path 165. For example, the electrical insulating bushing 150can be attached, pressed, or formed to the retainer 140 of the frame121. The electrical insulating bushing 150 is manufactured from anelectrical insulating material (e.g., plastic, rubber, polymer) and canbe inserted into the retainer 140. In some embodiments, the bushing 150is positioned within the retainer 140 near a front end of the frame 121.The bushing is then slid along the insertion path 165 (See FIG. 3)within the retainer 140 until the bushing 150 is securely seated withina rear of the frame 121. For example, a technician inserts a wire from afront end of the frame 121 of the connector 120 to a rear end of theframe 121 of the connector 120, the wire can contact the bushing 150,thereby exerting a force on the bushing 150, causing the bushing 150 toslide (e.g., translate) along the insertion path 165 with the movementand ultimate placement of the wire through the connector 120 and intothe internal volume 114 of the electrical box 110.

The bushing can snuggly fit within the rear of the retainer 140, cansnap or press into place at the rear of the retainer 140 or otherwise bepositioned within the retainer 140 to electrically isolate (e.g.,insulate) an electrical current carried by an electrically conductivewire from inadvertently electrically contacting (e.g., arcing, sparking)with one or more electrically conductive features of the electricalconnection assembly 100. For example, turning back to FIG. 3, in someembodiments, the electrical insulating bushing 150 can extend around theinternal perimeter of the aperture 116 to partition the electrical wirefrom electrical contact or electrically arcing or sparking with one ormore of the electrically conductive frame 140, housing 111, or aperture116. By extending around the internal perimeter of the aperture 116, theelectrical insulating bushing 150 can also cover and shield sharpprotrusions that may exist around the internal perimeter of the aperture116 from otherwise snagging, tearing, cutting, or penetrating theelectrically insulated coating or protective sheath in which the wiremay be wrapped.

FIG. 11 is a perspective view of another embodiment of an electricalconnector 120 including an electrical insulating bushing 150 having amembrane 155, with some features removed for clarity. For example, forexplanation purposes, the frame 121 of the connector 120 as well as theelectrical box 110 are removed with the understanding that theelectrical insulating bushing 150 having a membrane 155 can be employedalone or with one or more features of the electrical connection assembly100 without departing from the scope of the disclosure. FIG. 12 is anexploded perspective view of the electrical connector 120 including theelectrically insulating bushing 150 having a membrane 155 of FIG. 11.When provided, the membrane 155 can function as a disc 115 (e.g.,knock-out, as described above) and may comply with certain electricalcodes that require an unused aperture 116 (e.g., an aperture 116 throughwhich no wire is placed) to be blocked, plugged, or otherwiseobstructed. Thus, in some embodiments, an electrical connector 120including an electrically insulating bushing 150 having a membrane 155can be provided with or without a corresponding disc 115 to obstruct theaperture 116. Providing the membrane 155 allows further flexibility to atechnician with respect to wiring configurations and compliance withcertain electrical codes that cannot otherwise be obtained with atraditional disc 115.

The membrane 155 can be a solid piece connected to a body 151 of thebushing 150 with a frangible attachment 157 that can be broken with atool (e.g., screwdriver, electrical wire). The frangible attachment 157can be broken as a separate step or simultaneously in a single step wheninserting a wire into the connector 120 along the insertion path 165,thereby reducing the number of steps a technician employs to connect awire to the electrical box 110.

The membrane 155 can be formed as part of the insulating bushing 150defining a cap or closed end of the bushing 150. In some embodiments,the membrane 155 can be positioned at a variety of locations within theretainer 140 relative to the body 151 of the bushing 150 to obstruct theinsertion path 165 leading to the aperture 116. Similarly, the membrane155 can be formed or positioned at a variety of locations within thebody 151 of the bushing 150 (e.g., between a first end and a second endof the bushing 150) to obstruct the insertion path 165 leading to theaperture 116. In some embodiments, the membrane 155 can obstruct theentire opening 159 defined in the body 151 of the bushing 150 tocompletely cap or close the opening 159. Alternatively, the membrane 155can at least partially obstruct the opening 159 of the bushing 150 to atleast partially cap or close the opening 159. The membrane 155 functionsas the disc 115 until the frangible attachment 157 is broken and themembrane 155 is released. Once the frangible attachment 157 is broken,the opening 159 of the bushing 150 is unobstructed to permit insertionof a wire along insertion path 165 (as shown in FIG. 3). The frangibleattachment 157 can be manufactured from the same or different materialof either one of the membrane 155 and a body of the bushing 150 suchthat the attachment 157 breaks, fails, separates, or otherwisedisconnects the membrane 155 from a body of the bushing 150 uponapplication of a force.

In addition or alternatively, the membrane 155 itself can be formedentirely or partially from a frangible material such that a force (e.g.,contact by a tool, contact with a wire) breaks, pierces, tears, orotherwise disables the membrane 155 to permit insertion of wires throughthe connector 120 and into the electrical box 110. The frangiblematerial of the membrane 155 can be manufactured from a variety ofmaterials such as plastic, a brittle material, an elastic or elastomericmaterial that fails under a predetermined stress, or a rubber or otherpierceable (e.g., locally penetrable) material that fails when exposedto a predetermined force or stress. In some embodiments, the frangiblematerial of the membrane 155 can be defined as failing upon applicationof a predetermined stress where the predetermined stress is less than astress at which a body of the bushing 150 fails upon application.

FIGS. 13-17 show alternate embodiments of the electrical bushing 150with optionally reusable membranes. For example, FIG. 13 shows amembrane 180 with one or more tabs 181 extending from a backside 183 ofthe membrane 180. The tabs 181 are configured to engage with a channel182 that extends circumferentially about the inner diameter of theopening 159 of the body 151 of the bushing 150. For example, the tabs181 can include a flange, lip, protrusion, or other extending structureconfigured to contact the channel 182 to retain the membrane 180 in aposition obstructing the opening 159. The channel 182 is recessedrelative to the inner surface of the opening 159 such that the tabs 181position and secure within the channel 182 to retain the membrane 180 inthe bushing 150. While in the illustrated embodiment, the channel 182fully circumscribes the opening 159, in alternative embodiments, thechannel 182 can be formed as one or more segmented channels that atleast partially circumscribe the opening 159.

As with other examples discussed herein, a technician can remove themembrane 180 from the opening 159 with a tool or by manually applying aforce (e.g., with a finger or with a cable) to disengage the one or moretabs 181 from the channel 182. The tabs 181 may be resilient and flex tooptionally allow replacement of the membrane 180 in the opening 159 onceremoved. Thus, the membrane 180 with tabs 181 can optionally be reusedone or more times within the bushing 150 (e.g., removed and replaced) toobstruct the opening 159 of the bushing 150 or permit access through theopening 159 of the bushing 150. The reusable nature of the membrane 150allows a technician to reconfigure an electrical box assembly 100 at anytime (e.g., during installation or at a later time should wiringobjectives change). Additionally, in some embodiments, the membrane 180with tabs 181 can be removed from the opening 159 by disengaging thetabs 181 from the channel 182 with less force than may be applied toremove a metal knockout. Thus, the membrane 180 with tabs 181 may enablefaster installation and better user experience for technicians.

FIG. 14 provides another embodiment of a reusable membrane 184 havingone or more flanges 185 extending from a backside 187 of the membrane184. The flanges 185 are configured to engage a lip 186 on the innerdiameter of the opening 159. The lip 186 is raised relative to the innersurface of the opening 159 such that the flanges 185 position and secureagainst the lip 186 to retain the membrane 184 in the bushing 150. Forexample, the flanges 185 can flex inward (e.g., elastically deform) whenpositioning the membrane 184 in the opening 159 clearing the lip 186.The flanges 185 can then spring back outward to contact the lip 186 oncethe membrane 184 is positioned within the opening 159. The engagementbetween the flanges 185 and the lip 186 secures the membrane 184 withinthe bushing 150. The lip 186 can fully circumscribe the opening 159 orbe formed as one or more segmented lips that at least partiallycircumscribe the opening 159. As with the reusable bushing 180 of FIG.13, the bushing 184 of FIG. 14 is optionally reusable and provides thesame or similar advantages discussed above.

FIG. 15 provides another embodiment of an optionally reusable membrane188 with tabs 189. As compared to the membranes 180, 184 of FIG. 13 andFIG. 14, the tabs 189 of membrane 188 are formed at an edge 191 of themembrane 188 rather than extending from a backside of the membrane. Theinner surface of the opening 159 can include at least one of a channeland a lip 190 similar to the channel 182 and lip 186 discussed above.The tabs 189 are configured to engage the channel or lip 190 to retainthe membrane 188 within the bushing 150. Although illustrated as aplurality of tabs 189, in some embodiments, the membrane 188 can includea single tab formed along the entire edge 191 of the membrane 188.

FIGS. 16 and 17 show yet another embodiment of an optionally reusablebushing 195 with a hinge 199 connecting the membrane 195 to the body 151of the bushing 150. The membrane 195 includes one or more tabs 196 thatengage with at least one of a channel and a lip 197 to allow removal andreplacement of the membrane 195 in the opening 159. The hinge 199connects the membrane 195 to the bushing 150 when the membrane 195 isobstructing the opening 159 (shown in FIG. 16) and when the membrane 195is removed to allow access through the opening 159 (shown in FIG. 17).The hinge 199 can be formed as an integral component connecting themembrane 195 and the bushing 150 and may be configured to bend and flexwithout breaking. The hinge 199 may be a barrel hinge, a living hinge,or any other type of hinge. In addition to the advantages discussedabove with respect to reusable membranes, the membrane 195 with a hinge199 stays attached to the bushing 150 at all times and reduces thelikelihood of losing or misplacing the membrane 195 and ensures themembrane 195 is available to be replaced and reused by any technicianservicing the electrical assembly 100.

FIG. 18 is a perspective view of the electrical connection assembly 100including the electrical box 110, the electrical connector 120, and asupport bracket 130. The support bracket 130 includes a first end 131and a second end 132 (not visible in this view). The first end 131 caninclude one or more wiring accessories to facilitate positioning,placement, and support of wires or cables connected to the electricalbox 110 with the electrical connector 120. For example, FIG. 19 is aperspective view of a clip 160 for cable management oriented to attachto the first end 131 of the support bracket of FIG. 18. The clip 160includes fingers 161, 162 oriented to clasp and retain cables in a neat,controlled, and manageable fashion. The clip can be secured to the firstend 131 of the support bracket with one or more fasteners (e.g., screw,bolt, rivet, peg, pin, adhesive, material bonding technique, weld) andcan be selected to include a particular size, shape, or featuredepending on, for example, the type, amount, and size of wire connectedto the electrical box 110.

As shown in FIG. 20, which is a partial rear view of the electricalconnection assembly 100 including the electrical box 110, the electricalconnector 120, and a support bracket 130 of FIG. 18, the second end 132of the support bracket 130 connects to the electrical connector 120 orthe electrical box 110 with a fastener 135 (e.g., screw, bolt, rivet,peg, pin, adhesive, material bonding technique, weld). The cablemanagement clip 160 is cantilevered from the electrical box 110 or theelectrical connector 120 by the support bracket 130. The support bracket130, either alone or in combination with the clip 160, support theelectrical wire at a predetermined distance from the connector 120.Certain electrical codes may specify a particular predetermined distancemeasured from the electrical box 110 or the electrical connector 120 atwhich the wire is to be supported. Accordingly, in some embodiments, thesupport bracket 130 and the clip 160 can be selected to satisfy certainelectric codes while providing additional support for the wiresconnected to the electrical box 110 with the connector 120.

FIG. 21 is a plan view of a sheet of material 205 (e.g., metal, plastic,polymeric) including a pattern 203 for providing an electricalattachment 200 for an electrical box 210 including an electricalconnector 210 in accordance with embodiments of the disclosure. Thesheet 205 can be a single, monolithic piece of material on which apattern 203 can be provided (e.g., drawn, imprinted, etched, cut,stamped, pressed, engraved) and from which the electrical attachment 200is formed. In further embodiments, the sheet 205 can include a pluralityof sheets that are mechanical attached (e.g., welded, bonded) togetherto provide a unitary sheet 205 on which the pattern 203 is provided andfrom which the electrical attachment 200 is formed.

A variety of features (e.g., protrusions, recesses, cutouts, bends,folds, seams, apertures, notches, flanges, tabs, and slots) can beformed (e.g., machined, manufactured, drawn, imprinted, etched, cut,stamped, pressed, engraved) on, in, and with the sheet 205. For exampleapertures 211, 212 of the electrical connector 210 can be formed alongwith fold lines 214 and a tab 225. Additionally, protrusions 215 and oneor more apertures 220 can be formed in the sheet 205.

FIG. 22 is a plan view of the sheet of material 205 of FIG. 21 afterperforming a method of manufacturing the sheet 205 according to thepattern 203 to provide the electrical attachment 200. The electricalconnector 210 is formed by folding or bending a segment of the sheet 205that is at least partially separated (e.g., severed, cut) from the sheet205 according to the pattern 203. For example, folding or bending thepatterned segment along lines 214 forms a frame of the electricalconnector 210 that includes apertures 211 and 212 through which anelectrical wire (not shown) can be placed. Similarly, tab 225 securesthe electrical connector 210 to the sheet 205 (e.g., by matingengagement, mechanical fastener, adhesive, material bonding technique)to hold the folded or bent segment defining the electrical connector 210in place. Protrusions 215 can facilitate positioning of and mechanicallysecure a retainer (e.g., retainer 140), and an electrical insulatingbushing (e.g., bushing 150, bushing 150 and membrane 155).

After forming the electrical connector 210, a portion of the sheet 205extending between a first end 201 and a second end 202 provides asupport bracket 206 (e.g., similar to support bracket 160). A clip 160can be attached to the first end 201, and an aperture 220 can be formedat the second end 202 of the attachment 200. In some embodiments, afeature can be provided at the first end 201 of the attachment 200 toretain the clip 160. The attachment 200 can then be mechanically coupledto an electrical box (e.g., electrical box 110) with a fastener (notshown) interacting with the aperture 220 to secure the attachment 200 tothe box 210 (e.g., an underneath side of the box).

FIG. 23 is a perspective view of the electrical attachment 200 of FIG.21 and FIG. 22 after being formed by the method of manufacturing thesheet 205 according to the pattern 203. The electrical attachment 200 isa unitary attachment including an electrical connector 210 and a supportbracket 206 that are integrally formed together. FIG. 24 is an end viewof the electrical attachment 200 of FIG. 23, and FIG. 25 is a side viewof the electrical attachment 200 of FIG. 23 showing the unitaryconstruction of the attachment 200 including an electrical connector 210and a support bracket 206.

The present disclosure provides several embodiments and features ofelectrical connectors 120 fixed to the outside of an electrical box 110that facilitate and support a variety of wiring configurations andelectrical components. The electrical connection assembly 100 achievessafe and effective distribution of electric power with the electricalbox 110 and the electrical connector 120 of the present disclosure.

FIGS. 26-28 show an alternate embodiment of an electrical assembly 300including alternate features for accommodating an alternate electricalconnector 320 (shown in FIG. 27 and FIG. 28). The assembly 300 issubstantially the same as the assembly 100 described above with respectto FIGS. 1-12, except for the differences discussed herein. Likereference numerals are used for like elements. As shown in FIG. 26, theelectrical box 110 includes a pair of apertures 315 oriented to provideaccess into the internal volume 114 of the housing 111.

As shown in FIG. 27, the apertures 315 are spaced apart and configuredto accommodate a larger electrical connector 320 that is configured toaccommodate larger cables 325. While the term “larger” is a relativeterm, for exemplary purposes, the pair of apertures 315 can be spacedapart from each other a non-standard distance to accommodate a largerconnector than that of apertures spaced a standard distance apart fromeach other. Standard can refer to a common size manufactured in view ofone or more of a safety code or manufacturing guideline defining theparticular parameters of a feature. Moreover, the pair of apertures 315is described to illustrate the versatility of an electrical connector320 of the present disclosure to accommodate a wide variety of shapes,sizes, and styles of cables. In addition to the pair of apertures 315,the electrical box 111 includes an eccentric opening 318 positioned in athird aperture 319 on a same side 312 of the electrical box 111 as thepair of apertures 315. Providing an eccentric opening 318 on the sameside 312 as the pair of apertures 315 enables the electrical box 111 andconnector 320 to accommodate a wide range of cables and electricalcomponents.

FIG. 28 shows a cross-sectional view of the electrical connectionassembly 300 taken along line 28-28 of FIG. 27. The electrical connector320 includes a frame 321 with a retainer 140 having one or more teeth145 extending radially inward from the frame 121 to clamp and grip thecable 325. The electrical insulating bushing 150 is securely seated inthe aperture 315 and circumscribes the insertion path 165. As shown, thebody 151 of the bushing 150 has a groove 152 and a flange 153 at aleading end. The groove 152 is dimensioned to mate with the aperture 315with the flange positioned in the internal volume 114 of the electricalbox and a trailing end of the body 151 of the bushing 150 positioned inthe retainer 140 or frame 321. Once positioned, the flange 153 andgroove 152 secure the bushing 150 in the aperture 315.

A plug 330 is positioned in an opening 154 of the electrical bushing 150to obstruct the insertion path 165. The plug 330 has flange portion 331with a larger dimension than the opening 154 of the bushing 150. Theplug further includes a plurality of resilient legs 335 extending fromthe flange portion 331. The resilient legs 335 are oriented to flex in aradial direction relative to the insertion path 165. For example, theresilient legs 335 can be oriented to provide a structure larger thanthe opening 154 that flexes inward in a radial direction relative to theinsertion path 165 when inserted into the opening 154. The resilientlegs 335 exert a radial force to friction fit the plug 330 within theopening 154 of the bushing 150. A tool can be used to remove the plug330 from the opening 154. Alternatively, as the cable 325 is insertedalong the insertion path 165, a leading end 326 of the cable 325 cancontact the plug 330 and exert a lateral force on the plug 330 thatcauses the resilient legs 335 to flex radially inward as the end 326 ofthe cable 325 pushes the plug 330 the opening until the plug 330 isdisplaced from the opening 154 and the insertion path 165 is notobstructed.

FIGS. 29-32 show an alternate embodiment of an electrical assembly 400including features substantially the same as assembly 100 and assembly300 described above, except for the differences discussed herein. Likereference numerals are used for like elements. When employed in avariety of applications, it is common to secure the electrical box 110(shown in FIG. 1) to a structure. Such structures include, but are notlimited to, studs, frames, supports, columns, braces, hardware,cabinets, cases, walls, and other structural members found in a varietyof applications where an electrical box 110 is employed. The electricalassembly 400 includes one or more brackets (shown in FIG. 29 and FIG.30) that may be used to secure the electrical box 110 to the structure.

Known electrical boxes and brackets may have limitations. For example,physical space may be limited, and the construction of the structuralmembers to which the electrical box is secured may present physicalconstraints in terms of how and where the electrical box can be mountedto the structure. Additionally, bracket geometries may limit the numberof electrical boxes that can be mounted to a structure, as well as howand where the electrical boxes can be mounted. Moreover, when mountingan electrical box to a structure, a user may encounter challenges withrespect to proper placement (e.g., height, alignment, orientation) ofthe electrical box relative to the structure, relative to otherelectrical boxes, and relative to other components that may be foundwithin a predetermined physical space defined by the structure, such asplumbing, insulation, electrical wiring, and additional structuralsupport members.

Accordingly, for safe and effective distribution of electric power,brackets and electrical boxes are needed that address the above-notedlimitations. The present disclosure provides an assembly for electricaldistribution including an electrical box and a bracket having featuresthat can be provided either alone or in combination to facilitate safeand effective electrical distribution while achieving advantages thatcannot be obtained by known electrical boxes and brackets.

FIG. 29 is a perspective view of one example of a bracket 410 of theelectrical assembly 400, and FIG. 30 is a perspective view of anotherexample of a bracket 510 of the electrical assembly 400. Same or similarfeatures between bracket 410 and bracket 510 are identified using thesame reference numerals. For simplicity and not limitation, features ofbracket 410 will be described with the understanding that bracket 510includes the same or similar features, unless otherwise noted.

With reference to FIG. 29, the bracket 410 includes a first flange 411and a second flange 412. The first flange 411 is configured to beconnected to the electrical box 110 (shown in FIG. 1) and the secondflange 412 is configured to be connected to a structure (shown in FIG.31). The first flange 411 can be coupled to the electrical box using oneor more fasteners (e.g., screw, bolt, rivet, peg, pin, adhesive,material bonding technique, weld).

The bracket 410 includes a corner 413 connecting the first flange 411with the second flange 412. The first flange 411 extends from the corner413 in a first direction 421 away from the corner 413, and the secondflange 412 extends from the corner 413 in a second direction 422 awayfrom the corner 413. The first direction 421 is different from thesecond direction 422. In the illustrated embodiment, the first direction421 and the second direction 422 are oriented perpendicular to eachother and the corner 413 extends linearly in a third direction 423 alongthe joint between the first flange 411 and the second flange 412. Thefirst direction 421, second direction, 422, and third direction 423define a three-dimensional Cartesian coordinate system.

The bracket 410 is shown as having an inverted corner 413 configured toreceive a cover (not shown) and maintain the cover flush with the secondflange 412 and the open face of the electrical box 110. In otherembodiments, the corner 413 can be a standard or non-inverted corner, aninverted or non-inverted rounded corner, or corner having other linear,non-linear, or polygonal shapes depending on the type of cover orparticular application in which the assembly 400 is employed.

The second flange 412 includes a first edge 431, a second edge 432, anda third edge 433 that form a continuous perimeter of the second flange412 and define a central body portion 435 of the second flange 412within the continuous perimeter and delimited by the corner 413. Thecentral body portion 435 is shown as a planar surface, although thecentral body portion 435 can include non-planar surfaces in otherembodiments. The first edge 431 and the third edge 433 intersect at afirst intersection 441, and the second edge 432 and the third edge 433intersect at a second intersection 442.

The first intersection 441 is spaced a first distance “d1” from thecorner 413, and the second intersection 442 is spaced a second distance“d2” from the corner 413. The first distance “d1” does not equal thesecond distance “d2.” In the illustrated embodiment, the first distance“d1” is greater than the second distance “d2,” although the seconddistance “d2” can be greater than the first distance “d1” is otherembodiments.

The central body portion 435 includes a first aperture 451 positionedbetween the first edge 431 and the third edge 433 and a second aperture452 positioned between the second edge 432 and the third edge 433.Relative to the corner 413, the first aperture 451 is spaced a greaterdistance from the corner 413 than the distance the second aperture 452is spaced from the corner 413. In other embodiments, where “d2” isgreater than “d1,” the second aperture 452 is spaced a greater distancefrom the corner 413 than the distance the first aperture 451 is spacedfrom the corner 413. Spacing the apertures 451, 452 at offset locationswithin the central body 435 relative to the corner 413 may betterstabilize and prevent rotation of the electrical assembly 400 than twoequally spaced apertures.

As further shown in FIG. 29, the third edge 433 includes an inflectionpoint 460 where the third edge 433 changes from a convex profile 461 toa concave profile 462. The convex profile 461 extends from the firstintersection 441 to the inflection point 460, and the concave profile462 extends from the second intersection 442 to the inflection point460. The third edge 433 defines a continuous profile extending betweenthe first intersection 441 and the second intersection 442. Theinflection point 460 is midway between first intersection 441 and thesecond intersection 442, although the inflection point 460 can belocated at any location along the third edge 433 in other embodimentswithout departing from the scope of the disclosure.

Additionally, where “d2” is greater than “d1,” a concave profile canextend from the first intersection 441 to the inflection point 460, anda convex profile can extend from the second intersection 442 to theinflection point 460. Alternatively, as shown with respect to FIG. 30,the third edge 433 can extend linearly from the first intersection 441to the second intersection 442 defining a linear profile 465 oriented ata non-parallel angle relative to the corner 413. In other embodiments(not shown), the third edge 433 can include one or more featuresincluding planar and non-planar profiles and one or more inflectionpoints.

FIG. 31 shows a perspective view of the electrical assembly 400including the bracket 410 of FIG. 29 attached to the electrical box 110of FIG. 1. Although not shown, it should be understood that the bracket510 of FIG. 30 could similarly be attached to the electrical box 110 ofFIG. 1, without departing from the scope of the disclosure. The assembly400 is mounted to a structure 610 with one or more fasteners 615 (e.g.,screw, bolt, rivet, peg, pin, adhesive, material bonding technique,weld) secured within the first aperture 451 and the second aperture 452(shown in FIG. 29). The structure 610 is illustrated as a stud 610 withthe understanding that the structure 610 can include one or more studs,frames, supports, columns, braces, hardware, cabinets, cases, walls, orother structural members in other embodiments.

The bracket 410 and electrical box 110 are supplied to a technician as acompleted assembly 400 with the bracket 410 fixed to the electrical box110. Alternatively, the bracket 410 is provided alone or in combinationwith the electrical box 110 as a separate component that a technicianfastens to the electrical box 110 to provide a completed assembly 400.The assembly 400 is mounted to the structure 610. In some embodiments, aplurality of assemblies 400 can be mounted to the structure 610. Forexample, in the illustrated embodiment, two assemblies 400 are mountedto the structure 610. The bracket 410 includes a marker 415 representingone or more of a location or position of the bracket 410 relative toanother object (e.g., another bracket, a structure 610). The marker 415can be a visual marker (e.g., color, paint, sticker) or a physicalmarker (e.g., notch, scribe, ridge).

When fastened to the electrical box 110, the first flange 411 isattached to a side of the exterior surface 112 of the housing 111 of theelectrical box 110, and the second flange 412 extends away from the sideat a non-parallel angle relative to the first flange 411. The firstflange 411 and the second flange 412 are perpendicular to enablemounting of the assembly 400 on the structure 610 having a flat orplanar surface parallel to the open face of the box 110. The secondflange 412 is mounted to the structure 610 with the open face of the box110 parallel to the second flange 412. In other embodiments, thestructure 610 may include non-planar surfaces, or the assembly 400 maybe mounted on a structure with the open face of the box 110 non-parallelto the second flange 412.

FIG. 32 shows an enlarged view of a portion of the assembly 400 of FIG.31 for better clarity. Two brackets 410 a, 410 b are shown. Forexplanation purposes, features corresponding to bracket 410 a areidentified as “Xa,” and features corresponding to bracket 410 b areidentified as “Xb,” where X corresponds to the reference numerals of thefeatures described herein. As shown, when mounted side-by-side at thesame elevation, the brackets 410 a, 410 b are structured to bepositioned in mating relationship relative to each other. For example,bracket 410 b is identical to bracket 410 a and is oriented or rotated180 degrees about the inflection point 460 b such that the third edge433 b of bracket 410 b corresponds in profile to the third edge 433 a ofbracket 410 a to provide a complementary mating engagement between thebrackets 410 a, 410 b.

The third edge 433 a of bracket 410 a mirrors the third edge 433 b ofbracket 410 b. Inflection point 460 a of bracket 410 a is aligned withinflection point 460 b of bracket 410 b so that the convex profile 461 aof bracket 410 a mates with the concave profile 462 b of bracket 410 b,and the concave profile 462 a of bracket 410 a mates with the convexprofile 461 b of bracket 410 b. This mating relationship between thethird edge 433 a of bracket 410 a and the third edge 433 b of bracket410 b provides both a structural and visual guide to a technicianmounting the assembly 400 on a structure 610.

For example, in some applications, as illustrated, it may be desirableto mount at least two electrical boxes side-by-side at the sameelevation. Additionally, marker 415 a of bracket 410 a is aligned withmarker 415 b of mating bracket 410 b to provide the brackets 410 a, 410b at the same height on the structure 610. The markers 415 a, 415 b areshown as scribe lines and can include other shapes such as arrows, dots,text, and detents. The brackets 410 a, 410 b of the present disclosureenable a technician to accomplish this objective in a reduced time andwith greater accuracy and reliability than known methods using knownbrackets.

The brackets 410 a, 410 b are sized and shaped to enable placement oftwo brackets 410 a, 410 b side-by-side at the same elevation on the samestructure 610. The size and shape of the brackets 410 a, 410 b may bepredetermined and selected based on a predetermined dimension of thestructure 610. For example, the size and shape of the brackets 410 a,410 b may be predetermined and selected based on the dimension of astud. The brackets 410 a, 410 b can be manufactured from a variety ofmaterials (e.g., metal, plastic, polymeric) and can be a single,monolithic piece of material on which a pattern can be provided (e.g.,drawn, imprinted, etched, cut, stamped, pressed, engraved) and fromwhich the brackets 410 a, 410 b is formed (e.g., machined, manufactured,drawn, imprinted, etched, cut, stamped, pressed, engraved).
